EASA SIB 2014-12: Non-conforming Standard Hardware

What to do

Affected stakeholders should review the FAA SAIB HQ-14-16 for detailed recommendations regarding the identification and management of non-conforming fasteners. They should verify whether any purchased or installed fasteners fall under the affected categories and take appropriate corrective actions as advised. For further information or clarification, stakeholders are encouraged to contact the EASA Safety Information Section via the provided email address. No mandatory compliance deadline is specified.

Summary

EASA Safety Information Bulletin 2014-12 titled Non-conforming Standard Hardware addresses concerns about potentially non-conforming Military Specifications (MS), Army Navy Standards (AN), and National Aerospace Standards (NAS) fasteners used in civil aviation. The bulletin applies to manufacturers, owners, operators, and maintenance personnel of aircraft, engines, propellers, parts, and appliances. It aligns with the FAA Special Airworthiness Information Bulletin HQ-14-16 and aims to raise awareness of these hardware issues within EASA member states.

What changed

EASA SIB 2014-12 introduces detailed information on non-conforming standard hardware, specifically fasteners that may not meet Military Specifications, Army Navy Standards, or National Aerospace Standards. It endorses the FAA's findings and recommendations from SAIB HQ-14-16, providing additional clarity and guidance for stakeholders in civil aviation. This bulletin updates and expands upon the earlier EASA SIB 2012-06R2 on the same subject.

Why it matters

This bulletin is important for aviation professionals because non-conforming fasteners can compromise the safety and airworthiness of aircraft, engines, propellers, and related components. Operators, maintenance organizations, and manufacturers need to be aware of these issues to ensure compliance and maintain the integrity of their equipment. Early identification and proper handling of affected hardware help prevent potential failures and maintain regulatory compliance within EASA member states.
